A young wheelchair user is being suspended over a pond on the end of a long lever. Two men are holding the other end of the pole, which is fastened to a pivot point. A sign is placed next to the pond which reads ‘ATOS Test’. She is looking very apprehensively at two other men who are standing on the bank opposite. One of them is David Cameron who is listening to the other man say: “If she floats then she’s a fake, but if she drowns then she really is a disabled person!”
